摘　　要：从P2P网络开放性、分布性、动态性等特点出发,给出了P2P环境下基于信任值的信任管理语言,实现了信任关系的初始建立。针对安全凭证链的查找问题,结合P2P网络的特点,提出了使用结果安全凭证并结合基于最小安全凭证图的安全凭证链查找算法,提高了安全凭证链的查找效率。Because of the open, distributed and dynamic characteristics of peer to peer （P2P）, the security problem has become more difficult. Considering the creation of the trust relationship among entities, a language of trust management based on trust value named LOTOV was proposed. To improve the discovery of the certificates chain effectively, a searching algorithm based on minimal certificate-graph using certificate result certificate was designed and implemented. The experiments show the good performance of the approach.
